Disc brake equipment

Abstract

The invention relates to disc brake devices. The braking unit (72) of the disc brake device consists of: contact parts (72b, 72f) to press the brake pads (48L, 48R) inward in the radial direction of the brake disc (16); connecting parts (72cf 72e) connected to the contact parts (72b, 720); and extensions (72g, 72h) added in the connecting parts (72c, 72e) and reduce the stress concentration at the connecting parts (72c, 72e) by being wider in the axial direction (W) of the brake disc (16) than at any other location in the connecting parts (72c, 72e).
